Harmony Track on XG MIDI Files not working - did on Tyros 5

[keithvenn]

When I had a Tyros 5, I sometimes used XG MIDI files with harmony control built into them. Playing the left hand part of the Tyros did not affect the harmony, it was taken from the MIDI file.

When I try and do this on the Genos, it works until I press one of the keys on the left-hand part of the keyboard. Then, I get no harmony from the harmony track in the MIDI file.

Is there a setting that needs changing on the Genos please?
